Background
In the cement production process, two or more materials need to be ground when one ton of cement is produced, and the power consumption of grinding accounts for 65-70% of the power consumption of the whole plant. In the cement grinding process, the mixture ratio of materials is different due to different activities of mixed materials and different varieties of cement. When the difference between the grindability of the cement clinker and the grindability of the used mixed materials is large, and the materials are proportioned according to a certain proportion and then mixed and ground, the components which are difficult to grind are difficult to reach the optimal fineness, so that certain waste is caused; the components easy to grind are easy to generate over-grinding phenomenon, the machine-hour output of the grinding machine is influenced, and the grinding power consumption is increased. For example, when slag is used as a mixed material, the particle size of the slag after mixed grinding is larger than that of clinker powder, when the specific surface area of cement reaches a control index, the specific surface area of the slag is lower, the activity cannot be fully exerted, and if the activity of the slag is fully exerted, the excessive grinding can cause the over-grinding phenomenon of clinker, so that the service performance of the cement is poor, the yield is reduced, the power consumption is increased, and the economic production is not facilitated. Therefore, the production process of adopting separate grinding is the trend of cement grinding development in the future. The clinker and the mixed material are respectively ground by adopting different specific surface area control indexes to obtain cement components with reasonable particle distribution, the cement components are respectively stored in different clinker powder storehouses and mixed material powder storehouses, and the ground clinker powder and the mixed material powder are accurately metered by a metering scale according to the proportioning requirements of different types of cement and are fully stirred by a professional homogenizing and mixing device to prepare the required types of cement. In the process, different clinker powders and mixed material powders can be quickly and fully homogenized and mixed, and the method is very important for quickly switching cement varieties and producing cement products with different purposes and high performance.
